WebThe testing procedure: Easy and fast usage. Test bolts M20 to M72 (3/4" to 3") are directly mounted to the quick-clamp mechanisms of the measuring device. The bolt tensioning cylinder is threaded onto the test bolt and the coupling is connected to an integrated ITH hydraulic pump (ITH Hydro-MAX 38 in standard) WebApply the Pressure A as described in the tensioning procedure from 8 to 14. 4. Remove the tensioners from the bolts A and Insert the tensioners on B bolts as above. Apply the pressure B on the bolts as described above in 100% tensioning from step 6-14. 5. Check the break loose pressure of the bolt by putting tensioners on bolts A.

WebTensioning operation Step 1.. The bolt tensioner is fitted over the stud Step 2.. Hydraulic pressure is applied to the tensioner which then stretches the stud Step 3.. The stud's nut is wound down against the joint face Step 4.. Pressure is released and the tool removed WebAny project,any time. We apply the full spectrum of bolting & torquing tools and techniques (e.g. ultrasonic bolt load measurements) to give you a leak-free & reliable facility. Our seasoned technicians are ready to take on any challenge, understanding that safety remains the #1 priority when executing work in a live facility. WebHowever, all flange designs and geometry do not allow to use 100% tensioners. 50% tensioning means, we use 50% tensioners to bolt ratio. This means that every alternate bolt will have tensioners and would need to be tightened in two-stages. First stage with pressure A, and second stage with pressure B. Bolts are marked as 1 and 2, and … dječji vrtić montessori malešnica
